Mainly because of the low availability of components in my country, since ordering online would take me many months with this pandemic
also with that dac we can make the speed oscillate obtaining a kind of vibrato

Re: what would be the best delay based on pt2399?

I have only made EQD Disaster Transport Jr and Deep Blue Delay. Disaster Transport seemed to have a lot more clarity, and I really like it for guitar. Could probably try using a more hi-fi chip than the original TL072 for it too. For bass I prefer Deep Blue Delay, since it seems deeper and bassy. w...

what would be the best delay based on pt2399?

I found some pt2399 in my component box and I want to build a delay but there are many models on the net and I would like to know which one is the best in terms of clarity (I know that the pt2399 is already a bit noisy) but I would like to know Any recommendation

And, yes, installation of color switch is shown on the schematic mentioned above. yes i was referring to the color switch i installed th...

Re: small stone (lm13600 or 13700

The EHX - Small Stone ( LM13600 ) thread in the Circuit Analysis > Modern Stompbox Effects (1975 - ...) forum has a schematic. For a more modern approach you could study Build Your Own Clone (BYOC)'s Phase Royal OTA Phaser Module , which contains only the effect circuit and needs the Phase Royal , ...

Has anyone the schematic or any information on this pedal? These are the files that I was able to collect from that thread, credits to...
